Jenner's map has a scale line of 10 miles, chequered in
miles. This is neatly fitted in beside Simmons's table, at
a peculiar angle to the map.
Estimating from the scale line, 11mm, the map scale is
about:-
1 to 1500000
23 miles to 1 inch.
A better estimate of scale can be made from town positions, comparing known town-town distances, using DISTAB.exe. The map scale is about:-
1 to 1600000
25.5 miles to 1 inch.
The map maker's mile is probably an old english mile =
1.10 statute miles, BUT this is too small a map to give
a reliable estimate of the size of the old english mile.
A pair of dividers are drawn over the scale line. These
are distorted; to make them fit the space one leg is much
longer than the other.
